Tool 200i188L010C

Small diameter aluminum work amplifies every mistake. At 3/16", heat builds faster, chips pack tighter, and built-up edge formation accelerates. The workpiece size often means less rigidity, so chatter becomes another variable to manage.

This 3/16" end mill runs three flutes with high helix geometry designed for aluminum, copper, and plastics.
The flute count reduces chip load per tooth while maintaining productive feed rates.
That's what actually prevents adhesion buildup rather than just running slower.
TiB₂ coating adds hardness for demanding cuts without the aluminum affinity issues you get with AlTiN.
The R0.01" corner radius strengthens the cutting edge against microfracture while still maintaining sharp enough geometry for clean entry.
High helix promotes chip evacuation before heat accumulates in the cut zone.
